Sensor cleaning procedure
The cleaning procedure is slightly different for different types of sensors. In order to identify your sensor correctly please read this
knowledge base article.
Sensor cleaning procedure for TC sensors
can be found in the download section:
For AT sensors, please follow these guidelines:
- Remove the electrical power from the fingerprint sensor by disconnecting it from itspower source or unplugging it from the computer.
- Use any type of household kitchen or window cleaner, such as Formula 409™, Fantastic™, Windex™, or any generic versions of these cleaners.
- Do NOT use chlorine-based cleaners, such as Clorox™ bleach, non-chlorine bleach, or chlorine-based bathroom or mildew cleaners. Chlorine based cleaners will not necessarily affect the functionality of the fingerprint sensor, but they will discolor the finger drive ring and could damage the surrounding circuitry around the fingerprint sensor.
- Do NOT use any solvents, such as acetone, MEK, TCE, paint thinner, turpentine, etc. Solvents may attack the sensor surface coating or damage the flex tape (in COF sensors), surrounding enclosure or peripheral components to the sensor.
- Wet one end of a cotton swab or ear swab (not soaking or dripping wet) with one of the above mentioned cleaners. Gently rub the sensor surface and finger drive ring with the wet swab, slowly rotating the swab so a new, clean surface of the swab is constantly exposed to the sensor surface. Do not allow cleaner to drip or run down into the electronics around the sensor.
- After cleaning with the wet swab, gently rub the surfaces again with a dry cotton swab. Use a clean swab each time the sensor is cleaned. (If a dirty swab is used, it may make the sensor dirty again.)
